Zusammenfassung: | The invention relates to a rapid inductive low-current switching-on and switching-off device and an arc striking structure processing method. The rapid inductive low-current switching-on and switching-off device is characterized by comprising a static side arc striking hook, an arc striking whip and a movable arc striking module, the processing method comprises the following steps: S1, processing a flexible conductive rod body blank; s2, quenching and tempering heat treatment; s3, machining a static side arc striking hook; s4, processing the arc striking whip; by additionally arranging a static side arc striking hook and an arc striking whip structure, when the disconnecting switch is switched off, a moving contact is firstly separated by a certain distance, then the arc striking whip is switched off at a high speed, and an arc is quickly switched on, so that the contact is firstly switched on before the contact and a contact finger are contacted, and then is separated after the contact and the contact finger |
